This study reports on the interrelations among several domains of gender typing (e.g., masculinity, sexualization, and sexism) as well as their relationships to self-esteem. A group of undergraduates (113 women and 54 men) between the ages of 18-42 were administered online questionnaires asking them about masculinity beliefs, internalized sexualization, sexist beliefs, and self-esteem. A positive relationship was found between masculinity beliefs and hostile sexism. Also, a positive relationship was found between sexualization through self-compromise and self-esteem. These findings differ from relationships found in adolescence, which suggests a developmental change that affects these beliefs in young adults. Implications for understanding gender development in emerging adults are discussed.
